features:
- vhost-user reconnect is a mechanism which allows a vhost-user frontend to
reconnect to a vhost-user backend in the event the backend terminates
either as a result of a graceful shutdown or a crash. This allows a VM
utilising a vhost-user interface to reconnect automatically to the backend
e.g. Open vSwitch without requiring the VM to reboot. In this release,
support was added to the neutron Open vSwitch agent and ``ml2`` driver for
vhost-user reconnect.
other:
- vhost-user reconnect requires dpdk 16.07 and qemu 2.7 and openvswitch 2.6
to function. if an older qemu is used, reconnect will not be available but
vhost-user will still function.
